Asus P9X79 PRO b2 q-code details
Hello, I see the problem involves your Asus P9X79 PRO system. On startup you're receiving a B2 Q-Code, which indicates a Legacy Option ROM Initialization. This happens even though the AMD FirePro v9800 GPU is working correctly, so it's likely related to another component or configuration setting. Check the BIOS/UEFI options for any changes that might affect legacy modes or boot processes.
In reality, the issue was the power supply. It seems the GPU wasn't getting enough power, while the motherboard was struggling. The other GPU I checked had significantly less power.
